Purpose Of Review: We review the latest screening and diagnostic techniques, and the most recent recommendations on the management of hydroxychloroquine retinopathy.
Recent Findings: Hydroxychloroquine (HCQ) has been shown to cause retinal toxicity in a dose-dependent fashion. Early diagnosis is critical as the resultant retinopathy is not reversible.
Semiautomated computer software (ie, ROPtool) can trace and analyze optical coherence tomography (OCT)-generated retinal vessel maps for plus/pre-plus disease with high reliability and accuracy. This proof-of-concept study found that ROPtool can reliably rank OCT-generated vessel maps for tortuosity and combined tortuosity/dilation, which correlated well with human-expert rankings and clinical examination.

Methods: For infants enrolled in BabySTEPS, ophthalmologists recorded fundus pigmentation (blond, medium, or dark) at the first retinopathy of prematurity (ROP) examination. Bedside OCT imaging was performed at each examination, and a masked grader evaluated all OCT scans from both eyes of each infant for visibility (yes/no) of all retinal layers and of the chorio-scleral junction (CSJ).
Background/aims: The optic nerve development during the critical postnatal weeks of preterm infants is unclear. We aimed to investigate the change of retinal nerve fibre layer (RNFL) in preterm infants.
Methods: We used an investigational handheld optical coherence tomography (OCT) system to serially image awake preterm infants between 30 and 60 weeks postmenstrual age (PMA) at the bedside.
En face retinal vessel maps generated from bedside optical coherence tomography (OCT) can show posterior pole vascular tortuosity and dilation (ie, plus/pre-plus disease). In this proof-of-concept study, we found that ROPtool could trace OCT-generated retinal vessel maps with high reliability and accuracy for detecting plus or pre-plus disease.

Objective: To evaluate the association between preterm infant retinal microanatomy and VA at 9 months' corrected age.
Importance: Early diagnosis of plus disease is critical in the management of retinopathy of prematurity (ROP). However, there is substantial interexpert disagreement in the diagnosis of plus disease based on vascular changes alone. Information derived from optical coherence tomography (OCT) may help characterize the severity of vascular and structural abnormalities in ROP.

We report the use of investigational bedside noninvasive optical coherence tomography angiography to visualize the slow and progressive perifoveal vascular formation in an infant with AP-ROP treated with bevacizumab. We also document extensive vascular shunts and morphological differences between arrested and growing retinal capillaries at the vascular wavefront.

Methods: In this exploratory study, we selected images from eyes with a range of ROP vascular disease, prospectively acquired from preterm infants using an investigational, noncontact, handheld, bedside swept-source OCT. We autosegmented OCT volumes using custom infant-specific software, extracted RVSV-OCT images from volumetric data bracketed around the retinal pigment epithelium, and automontaged the resulting RVSV-OCT images.
